Torque Reduction

The Torque Reduction Function is used for drag racing bikes, to allow for the control of the engines acceleration during upshift gear changes. This control is achieved through the application of fuel and/or ignition pulse cuts, and ignition timing retard. This feature can only be used if a gear position sensor or a gear switch is being used to detect gear position. Torque reduction has 3D ignition retard tables for each gear shift, and an output available to be used for the gear shift solenoid.



Ignition Retard Time Limit - This is the maximum duration that the torque reduction will be applied for after initial activation.

Minimum Throttle Position - This is the minimum throttle position necessary for torque reduction to operate

Minimum RPM - This is the minimum RPM necessary for torque reduction to operate

Output Pulse Width - The pulse width used for the torque reduction output

Cut Type - This is the cut method used to reduce torque
No Cut - Disables any cut method from activating
Ignition Cut - Ignition Outputs will be cut to reduce torque. This is the more common method.
Fuel Cut - Injection Outputs will be cut to reduce torque.
Fuel & Ignition Cut - Injection Outputs and Ignition Outputs will be cut to reduce torque.
Input Select - This is the Input that will be used to trigger a reduction in torque
Gear Position Sensor - The gear position sensor will be used to determine a gear shift.
Gear Switch - The gear switch will be used to determine a gear shift.
